DOES THE 618 RETAIN A CHARGE?

I do not use my phone a lot, but I charge it about once a week and it lasts well.

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

The charge does decay. If you charge it over night it could get you out of a pinch during the day.

Yes, you can keep it constantly charged. I like this tool. I have a large cordless but this is great for finer work. It has a surprising amount of torque. Very pleased. You'll need to get a set of smaller bits for fine work.

No - I have been using mine about 6 weeks now, but within two weeks it went from an excellent charge to a "good charge." it took my manufacturer's battery five years to change the rating.

I have used many rechargeable devices over the years and, yes, with light use, it should hold its charge for a few years as other similar hand vacuums do. It seems that this is a defect and that Amazon should work with the manufacturer to rectify the situation. If they do not, I will certainly try not to buy any more Black & Decker products.

I have never removed this battery since I bought it and it has received several charges. i try not to leave it on the charger since I have heard, cell batteries in general, do not do well when left on the charger at a full charge.No specific issues with this specific battery however.

I have not had any problem with charging this model.The only issue that I had is with the hold switch. For a time, the unit would stay in hold or non-hold no matter what I did with the slider switch. For reasons that I do not understand, the problem went away one day and has not come back for more than six months.

Yes and the battery has a long duty cycle between recharges. If this battery is like the 12 volt version, it will hold its charge for a year after charging if it is not used.

I don't know. I always keep mine charged when I am not using it like my iPad.

Never thought about it, but it is the only unit that runs full time on that particular bill. The rest is infrequent tool use. Did not notice a change in charges.

Depends on the controller. Some have a series of colored LEDs indicating the charging rate, some have an LCD voltmeter showing the current state of charge. Almost all, including the least expensive, drop down to a trickle charge state as the battery approaches a full charge. A battery will lose some power just being stored. The solar charge controllers will keep it charged up automatically. As ever, it is best to fully research the capabilities and limitations of each mfr. Amazon user reviews have been very helpful for me. Hope this helps.

yes the indicator light does gradually change although I cannot remember the color indicating full charge I think it might be

It will maintain a charge, but if you're watching movies it may discharge even while plugged in. That's how mine does.

I don't remember if it had any charge when I got it, but I always fully charge the batteries so they are ready for use. I don't want them to die on me when I need them.

Yes. That's exactly why i bought it. Just need to keep an eye on charge status.

I know it holds a charge if turned off for awhile, but not sure it charges in the off position..It's winter so I haven't had it on for awhile...I think the system is great except for refilling the compartment all the time...They can't make the storage any greater due to weight, but still a pain....The system itself seems to work great and worth the money....
